That places this record below the midpoint for clinical cardiac electrophysiology clinicians in MO, where the typical reported total is $14,594.

Medicare billing

Part B allowed, 2024

$8,773

Medicare patients

Services billed

109

What this is not: this is the amount Original Medicare Part B allowed for services this provider billed in 2024. It is not their income. It excludes Medicare Advantage — now more than half of all Medicare enrollment — along with Medicaid and all commercial insurance, and it is gross practice revenue before staff, rent, supplies and malpractice premiums. CMS also suppresses any figure covering ten or fewer patients, so low-volume providers appear smaller than they are.
